A behind-the-scenes look at some of the work that has gone into NIST's laser welding program, whose goal is to understand how laser welding works on a fundamental level. Watch a high-power laser melt brick into glass, and see steel stretch like chewing gum in a weld strength test, as NIST scientists explain how this work might someday help manufacturers make medical devices, cars, airplanes, laptops, cell phones, and more.
